The DMCA, the Digital Millennium Copyright Act, was signed into law in 1998 in an attempt to address Copyright protection in the Digital Age.
TurboSquid is a DMCA compliant operation. This means that when we receive valid takedown notices from © or TM owners we act accordingly, and remove any infringing models brought to our attention.
That said, because of how the DMCA Safe Harbor provision works, and because of the realities any large open marketplace, we do not pro-actively police TM infringement to any degree that TurboSquid might guarantee that any particular model is not infringing. We can only work in a responsive mode. The burden to not infringe falls to TurboSquid's vendors, the individuals who create these assets and place them for sale on our site.

Also, as of April 2010, we have added Editorial restrictions which does allow for the use of products that may have copyrights or trademarks. Please see our FAQ on Editorial Use for more information.
